The article is devoted to the analytical solution of the problem of quality of draft laws, when the initial estimates are given verbally and based on different criteria. We consider well-known ideas and intellectual systems in the field of jurisprudence. Special attention is paid to the application of fuzzy logic, the concept of its development and integration with various methods. With dynamically developing public relations, legislators are increasingly faced with problems that are more or less correlated with the quality of bills. In a country that recognizes the inviolability of the law and legal norms, the effectiveness of laws is an important task for the legislator. Evaluating the quality of a legislative act at the stages of drafting bills requires the involvement of both social and formalized decision methods. Therefore, the process under study is considered in the scope of multi-criteria solution theory, where it is necessary to synthesize an algorithm for constructing a number of effective alternatives. In modern theories of decision-making methods, calculus of variations, and optimization, various methods of solving the problem can be used. This paper describes some possible variations of the source data setting. The algorithm that leads to erroneous responses is considered separately. An alternative version and an example of implementation are given.
